A rapid strategy to evaluate patient with suspected acute myocardial infarction included a baseline high sensitivity cardiac troponin T level, a repeat level in 1 hour, and observation care for equivocal cases. Within 1 hour, 40% of patients were classified as ruled-in or ruled-out, and 60% went on to observation care. The sensitivity and negative predictive value in the ruled-out group was over 99%. 30-day mortality was 0% in the ruled out group.

Comment: Applying this protocol would greatly decrease costs by decreasing standard observation care by categorizing patients quickly (within 1 hour).
